176 #define IBasicModule_iid "com.twsz.tc.ningjian.IBasicModule/1.0"

178 Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid)
179 
180 QT_END_NAMESPACE
181 
182 
183 //Q_DECLARE_INTERFACE(IBasicModule,"com.twsz.tc.ningjian.IBasicModule/1.0");
184 
185 #endif // BASIC_MODULE_INTERFACE_H

基本是纯虚类要在末尾添加  

Q_DECLARE_INTERFACE(IBasicModule, IBasicModule_iid) 即可

2、实现插件
头文件 如下：  cpp正常就好了，注意要继承QObject 和 接口类就可以了，还要在在头文件中添加
    Q_OBJECT
    Q_PLUGIN_METADATA(IID "com.twsz.tc.ningjian.IBasicModule/1.0" )
    Q_INTERFACES(IBasicModule)
在项目属性中要添加
TEMPLATE = lib
CONFIG += plugin

3、使用插件

下面是遍历加载plugins目录下所有实现 IBasicModule 接口的插件 获取相应的实例就可以调用了
头文件记得添加
#include <QPluginLoader>
 1     //注册模块指令
 2     QDir plugindir = QDir(QDir::currentPath()+"/plugins");
 3     int i = 0;
 4     foreach(QString filename,plugindir.entryList(QDir::Files)){
 5         QPluginLoader loader(plugindir.absoluteFilePath(filename));
 6         if (IBasicModule * base_moudle = qobject_cast<IBasicModule *>(loader.instance()))
 7         {
 8             qDebug()<<base_moudle->get_moudle_name().c_str();
 9 
10             STT_Global::basicModule_map.insert(std::pair<std::string,IBasicModule*>(base_moudle->get_moudle_name(),base_moudle));
11             STT_Global::PlugsList.push_back( base_moudle->get_moudle_name());
12             base_moudle->init(G_Test_Info,G_Test_Fun_Info,G_Moudles_Config,G_STT_Run_Fun);
13             base_moudle->reg_fun(-1,G_STT_Interpreter[-1]);
14             base_moudle->reg_ui_fun(G_Reg_UI_FUN);
15             i++;
16             emit STT_Global::fl->signal_process(20+ 80 * i / plugindir.entryList(QDir::Files).size());
17         }
18     }
